Abstract Arboricultural climbing is inherently dangerous and although previous studies have investigated forces associated with ascents, abrupt stops during descents, and simulated falls, no studies have measured forces for typical climbing actions. Neither have studies measured motion of a tie-in point (TIP) and branch as a climber walked on the branch. We measured forces at the TIP and accelerations at the TIP and on a branch as a climber performed arboricultural climbing actions using two climbing lines and three climbing systems. Neither forces nor accelerations differed between climbing lines or systems, but covariates related to branch and TIP morphology were significant predictors of forces and accelerations in mechanically intuitive ways. As expected, forces measured for typical arboricultural climbing actions were less than those measured for ascents, abrupt stops during descents, and simulated falls. Results provide an important baseline for future work and can inform arboricultural safety standards to reduce the likelihood of injury while climbing.

与树木攀爬相关的力和运动

摘要 树木栽培的攀登本质上是危险的，尽管之前的研究调查了与上升、下降过程中的突然停止和模拟坠落相关的力，但没有研究测量典型攀登动作的力。当登山者在树枝上行走时，也没有研究测量连接点 (TIP) 和树枝的运动。当登山者使用两条攀爬线和三个攀爬系统进行树木攀爬动作时，我们测量了 TIP 处的力以及 TIP 处和树枝上的加速度。攀爬线路或系统之间的力和加速度都没有差异，但与分支和 TIP 形态相关的协变量是机械直观方式的力和加速度的重要预测因子。正如预期的那样，为典型的树木攀爬动作测量的力小于为上升、下降过程中的突然停止和模拟跌落测量的力。结果为未来的工作提供了重要的基准，并可以告知树木栽培安全标准，以减少攀爬时受伤的可能性。
